Joan is setting up an experiment in the lab to observe newton's second law of motion. she has a model car that has a mass of 45 kg, and it is accelerating at 7 m/s/s. she then increases the acceleration to 28 m/s/s. what happens to the force of the car?

The force of the car increases because it is proportional to the acceleration of the object (as stated in the second law). If the object accelerates then the force accelerates, if the acceleration decreases then the force decreases. Same for mass. The force of the car would have changed from 315 newtons of force to 1,260 newtons of force.
